Abstract

There is obtained an increase in the throughput in the known BMA furnace or a BMA furnace chamber without changing the construction and dimensions already present by changing the lower part of the cooling head into a short tubular heat exchanger while maintaining the necessary temperature profile for the process by arranging the ceramic tubes in the furnace chamber in closer or less close fashion and/or by using ceramic tubes having different inner and outer geometries and/or structure.
